Understanding Telegram Data Centres (DCs) and Account Allocation

Conclusion

Telegram's account allocation is closely tied to its Data Centres (DCs). The country/region a user selects during registration determines which Data Centre their account belongs to, and this cannot be changed once registered. Understanding this information is crucial for optimising your Telegram experience.

Telegram Data Centre Overview

Telegram has established multiple Data Centres (DCs) globally to support its services, specifically including:

• DC1: USA - Miami
• DC2: Netherlands - Amsterdam
• DC3: USA - Miami
• DC4: Netherlands - Amsterdam
• DC5: Singapore

How to Confirm Your Account's DC

1. According to Telegram's official documentation, the DC an account belongs to is usually determined by the IP address at the time of registration.
2. In practice, the DC an account belongs to is determined by the country/region chosen during registration. For example, most +86 numbers are in DC5, while +1 numbers are typically in DC1.
3. The DC is set at registration and cannot be changed. Even if you change your phone number, the DC will not change. To change DCs, you must delete your account and register a new one.
4. You can check which DC your account belongs to using the following bots:
   • @Sean_Bot
   • @KinhRoBot
   • @nmnmfunbot

The Significance of Setting Up Proxy Strategy Groups for Telegram

1. The DC your account belongs to determines where your data (such as messages, images, files, etc.) is stored. When you send media in private chats or groups, recipients need to download this content from your DC.
2. For example, if your account is in DC5, regardless of which DC the recipient's account is in, viewing media you send will result in a download from DC5. Conversely, if the recipient's account is in DC1, viewing media they send will also result in a download from DC1.
3. After understanding the above two points, you'll realise there's no real practical benefit to setting up a separate proxy strategy group for Telegram. This is because group members might be spread across different DCs, and setting up a proxy strategy group would only increase download latency without a significant perceived difference.

Other Information

DC5 often has poor stability. Thinking of switching to DC1? However, DC1 and DC4 frequently experience issues too 😂
